The present invention provides piperidin-4-yl azetidine derivatives, aswell as their compositions and methods of use, that modulate theactivity of Janus kinase 1 (JAK1) and are useful in the treatment ofdiseases related to the activity of JAK1 including, for example,inflammatory disorders, autoimmune disorders, cancer, and otherdiseases.

BACKGROUND

Protein kinases (PKs) regulate diverse biological processes includingcell growth, survival, differentiation, organ formation, morphogenesis,neovascularization, tissue repair, and regeneration, among others.Protein kinases also play specialized roles in a host of human diseasesincluding cancer. Cytokines, low-molecular weight polypeptides orglycoproteins, regulate many pathways involved in the host inflammatoryresponse to sepsis. Cytokines influence cell differentiation,proliferation and activation, and can modulate both pro-inflammatory andanti-inflammatory responses to allow the host to react appropriately topathogens. Signaling of a wide range of cytokines involves the Januskinase family (JAKs) of protein tyrosine kinases and Signal Transducersand Activators of Transcription (STATs). There are four known mammalianJAKs: JAK1 (Janus kinase-1), JAK2, JAK3 (also known as Janus kinase,leukocyte; JAKL; and L-JAK), and TYK2 (protein-tyrosine kinase 2).

Cytokine-stimulated immune and inflammatory responses contribute topathogenesis of diseases: pathologies such as severe combinedimmunodeficiency (SCID) arise from suppression of the immune system,while a hyperactive or inappropriate immune/inflammatory responsecontributes to the pathology of autoimmune diseases (e.g., asthma,systemic lupus erythematosus, thyroiditis, myocarditis), and illnessessuch as scleroderma and osteoarthritis (Ortmann, R. A., T. Cheng, et al.(2000) Arthritis Res 2(1): 16-32).

Deficiencies in expression of JAKs are associated with many diseasestates. For example, Jak1−/− mice are runted at birth, fail to nurse,and die perinatally (Rodig, S. J., M. A. Meraz, et al. (1998) Cell93(3): 373-83). Jak2−/− mouse embryos are anemic and die around day 12.5postcoitum due to the absence of definitive erythropoiesis.

The JAK/STAT pathway, and in particular all four JAKs, are believed toplay a role in the pathogenesis of asthmatic response, chronicobstructive pulmonary disease, bronchitis, and other relatedinflammatory diseases of the lower respiratory tract. Multiple cytokinesthat signal through JAKs have been linked to inflammatorydiseases/conditions of the upper respiratory tract, such as thoseaffecting the nose and sinuses (e.g., rhinitis and sinusitis) whetherclassically allergic reactions or not. The JAK/STAT pathway has alsobeen implicated in inflammatory diseases/conditions of the eye andchronic allergic responses.

Activation of JAK/STAT in cancers may occur by cytokine stimulation(e.g. IL-6 or GM-CSF) or by a reduction in the endogenous suppressors ofJAK signaling such as SOCS (suppressor or cytokine signaling) or PIAS(protein inhibitor of activated STAT) (Boudny, V., and Kovarik, J.,Neoplasm. 49:349-355, 2002). Activation of STAT signaling, as well asother pathways downstream of JAKs (e.g., Akt), has been correlated withpoor prognosis in many cancer types (Bowman, T., et al. Oncogene19:2474-2488, 2000). Elevated levels of circulating cytokines thatsignal through JAKSTAT play a causal role in cachexia and/or chronicfatigue. As such, JAK inhibition may be beneficial to cancer patientsfor reasons that extend beyond potential anti-tumor activity.

JAK2 tyrosine kinase can be beneficial for patients withmyeloproliferative disorders, e.g., polycythemia vera (PV), essentialthrombocythemia (ET), myeloid metaplasia with myelofibrosis (MMM)(Levin, et al., Cancer Cell, vol. 7, 2005: 387-397). Inhibition of theJAK2V617F kinase decreases proliferation of hematopoietic cells,suggesting JAK2 as a potential target for pharmacologic inhibition inpatients with PV, ET, and MMM.

Inhibition of the JAKs may benefit patients suffering from skin immunedisorders such as psoriasis, and skin sensitization. The maintenance ofpsoriasis is believed to depend on a number of inflammatory cytokines inaddition to various chemokines and growth factors (JCI, 113:1664-1675),many of which signal through JAKs (Adv Pharmacol. 2000; 47:113-74).

Thus, new or improved agents which inhibit kinases such as JAKs arecontinually needed for developing new and more effective pharmaceuticalsthat are aimed at augmentation or suppression of the immune andinflammatory pathways (such as immunosuppressive agents for organtransplants), as well as agents for the prevention and treatment ofautoimmune diseases, diseases involving a hyperactive inflammatoryresponse (e.g., eczema), allergies, cancer (e.g., prostate, leukemia,multiple myeloma), and some immune reactions (e.g., skin rash or contactdermatitis or diarrhea) caused by other therapeutics. The compounds ofthe invention, as well as its compositions and methods described hereinare directed toward these needs and other ends.

An XRPD pattern of reflections (peaks) is typically considered afingerprint of a particular crystalline form. It is well known that therelative intensities of the XRPD peaks can widely vary depending on,inter alia, the sample preparation technique, crystal size distribution,various filters used, the sample mounting procedure, and the particularinstrument employed. In some instances, new peaks may be observed orexisting peaks may disappear, depending on the type of the machine orthe settings (for example, whether a Ni filter is used or not). As usedherein, the term “peak” refers to a reflection having a relativeheight/intensity of at least about 4% of the maximum peakheight/intensity. Moreover, instrument variation and other factors canaffect the 2-theta values. Thus, peak assignments, such as thosereported herein, can vary by plus or minus about 0.2° (2-theta), and theterm “substantially” as used in the context of XRPD herein is meant toencompass the above-mentioned variations.

In the same way, temperature readings in connection with DSC, TGA, orother thermal experiments can vary about ±3° C. depending on theinstrument, particular settings, sample preparation, etc. Accordingly, acrystalline form reported herein having a DSC thermogram “substantially”as shown in any of the Figures is understood to accommodate suchvariation.

It is further appreciated that certain features of the invention, whichare, for clarity, described in the context of separate embodiments, canalso be provided in combination in a single embodiment. Conversely,various features of the invention which are, for brevity, described inthe context of a single embodiment, can also be provided separately orin any suitable subcombination.

At various places in the present specification, substituents ofcompounds of the invention are disclosed in groups or in ranges. It isspecifically intended that the invention include each and everyindividual subcombination of the members of such groups and ranges. Forexample, the term “C₁₋₆ alkyl” is specifically intended to individuallydisclose methyl, ethyl, C₃ alkyl, C₄ alkyl, C₅ alkyl, and C₆ alkyl.

At various places in the present specification, linking substituents aredescribed. It is specifically intended that each linking substituentinclude both the forward and backward forms of the linking substituent.For example, —NR(CR′R″)_(n)— includes both —NR(CR′R″)_(n)— and—(CR′R″)_(n)NR—. Where the structure clearly requires a linking group,the Markush variables listed for that group are understood to be linkinggroups. For example, if the structure requires a linking group and theMarkush group definition for that variable lists “alkyl” or “aryl” thenit is to be understood that the “alkyl” or “aryl” represents a linkingalkylene group or arylene group, respectively.

At various places in the present specification, rings are described(e.g., “a piperidine ring”). Unless otherwise specified, these rings canbe attached to the rest of the molecule at any ring member as permittedby valency. For example, the term “a pyridine ring” may refer to apyridin-2-yl, pyridin-3-yl, or pyridin-4-yl ring.

The term “n-membered” where n is an integer typically describes thenumber of ring-forming atoms in a moiety where the number ofring-forming atoms is n. For example, piperidinyl is an example of a6-membered heterocycloalkyl ring, pyrazolyl is an example of a5-membered heteroaryl ring, pyridyl is an example of a 6-memberedheteroaryl ring, and 1,2,3,4-tetrahydro-naphthalene is an example of a10-membered cycloalkyl group.

For compounds of the invention in which a variable appears more thanonce, each variable can be a different moiety independently selectedfrom the group defining the variable. For example, where a structure isdescribed having two R groups that are simultaneously present on thesame compound, the two R groups can represent different moietiesindependently selected from the group defined for R. In another example,when an optionally multiple substituent is designated in the form:

then it is to be understood that substituent R can occur p number oftimes on the ring, and R can be a different moiety at each occurrence.It is to be understood that each R group may replace any hydrogen atomattached to a ring atom, including one or both of the (CH₂) hydrogenatoms. Further, in the above example, should the variable Q be definedto include hydrogens, such as when Q is said to be CH₂, NH, etc., anyfloating substituent such as R in the above example, can replace ahydrogen of the Q variable as well as a hydrogen in any othernon-variable component of the ring.

The SEM-protected intermediate 1-2 is subjected toa Suzuki coupling with a boronic acid of a protected pyrrole, such as1-(triisopropylsilyl)pyrrole-3-boronic acid (2-1), using a palladiumreagent, such as tetrakis(triphenylphosphine)palladium(0), in thepresence of a base. The coupling product of formula 2-2 can be convertedto the desired product of formula 2-3 in situ by carrying out thereaction overnight in the same media.

Intermediates of formula 3-7 can be prepared according to the proceduresshown in Scheme 3. A Boc-protected azetidinone of formula 3-1 issubjected to a Wittig reaction with a phosphonate, such as diethylcyanomethylphosphonate, in the presense of a base, such as sodiumhydride, to form a cyano derivative of formula 3-2. Michael addition ofintermediates of formula 1-5 or 2-3 to the derivative of formula 3-2 inthe presense of base, such as DBU produces the addition product offormula 3-3. Following removal of the Boc group (e.g., by using an acidsuch as 4 N HCl in dioxane), reductive amination of the resultingazetidine of formula 3-4 with a N-Boc protected piperidinone of formula3-5 using a reducing agent, such as sodium triacetoxyborohydride, givesrise to a compound of formula 3-6. Removal of the Boc group in thecompound of formula 3-6 (e.g., using an acid such as 4 N HCl in dioxane)affords the desired intermediates of formula 3-7.

Intermediates of formula 3-7 can be derivatized at the piperidinenitrogen to produce a series of compounds of Formula I as depicted inScheme 4. Reaction of the compound of formula 3-7 with a sulfonylchloride followed by treating first with TFA and then withethylenediamine to remove the SEM group yields sulfonamide derivativesof formula 4-1. Coupling of the compound of formula 3-7 with acarboxylic acid using a coupling agent such as BOP or with an acylchloride, followed by removal of the SEM group provides amide compoundsof formula 4-2. Reductive amination of the compound of formula 3-7 withan aldehyde using a reducing agent, such as sodiumtriacetoxyborohydride, followed by removal of the SEM group gives riseto the N-alkyl derivatives of formula 4-3. Reaction of the compound offormula 3-7 with an isocyanate, followed by removing the SEM groupaffords the urea compounds of formula 4-4.

Methods

Compounds of the invention are JAK inhibitors, and the majority of thecompounds of the invention, are JAK1 selective inhibitors. A JAK1selective inhibitor is a compound that inhibits JAK1 activitypreferentially over other Janus kinases. For example, the compounds ofthe invention preferentially inhibit JAK1 over one or more of JAK2,JAK3, and TYK2. In some embodiments, the compounds inhibit JAK1preferentially over JAK2 (e.g., have a JAK1JAK2 IC₅₀ ratio>1). In someembodiments, the compounds are about 10-fold more selective for JAK1over JAK2. In some embodiments, the compounds are about 3-fold, about5-fold, about 10-fold, about 15-fold, or about 20-fold more selectivefor JAK1 over JAK2 as calculated by measuring IC₅₀ at 1 mM ATP (e.g.,see Example A).

JAK1 plays a central role in a number of cytokine and growth factorsignaling pathways that, when dysregulated, can result in or contributeto disease states. For example, IL-6 levels are elevated in rheumatoidarthritis, a disease in which it has been suggested to have detrimentaleffects (Fonesca, J. E. et al., Autoimmunity Reviews, 8:538-42, 2009).Because IL-6 signals, at least in part, through JAK1, antagonizing IL-6directly or indirectly through JAK1 inhibition is expected to provideclinical benefit (Guschin, D., N., et al Embo J 14:1421, 1995; Smolen,J. S., et al. Lancet 371:987, 2008). Moreover, in some cancers JAK1 ismutated resulting in constitutive undesirable tumor cell growth andsurvival (Mullighan C G, Proc Natl Acad Sci USA. 106:9414-8, 2009; FlexE., et al. J Exp Med. 205:751-8, 2008). In other autoimmune diseases andcancers elevated systemic levels of inflammatory cytokines that activateJAK1 may also contribute to the disease and/or associated symptoms.Therefore, patients with such diseases may benefit from JAK1 inhibition.Selective inhibitors of JAK1 may be efficacious while avoidingunnecessary and potentially undesirable effects of inhibiting other JAKkinases.

Selective inhibitors of JAK1, relative to other JAK kinases, may havemultiple therapeutic advantages over less selective inhibitors. Withrespect to selectivity against JAK2, a number of important cytokines andgrowth factors signal through JAK2 including, for example,erythropoietin (Epo) and thrombopoietin (Tpo) (Parganas E, et al. Cell.93:385-95, 1998). Epo is a key growth factor for red blood cellsproduction; hence a paucity of Epo-dependent signaling can result inreduced numbers of red blood cells and anemia (Kaushansky K, NEJM354:2034-45, 2006). Tpo, another example of a JAK2-dependent growthfactor, plays a central role in controlling the proliferation andmaturation of megakaryocytes the cells from which platelets are produced(Kaushansky K, NEJM 354:2034-45, 2006). As such, reduced Tpo signalingwould decrease megakaryocyte numbers (megakaryocytopenia) and lowercirculating platelet counts (thrombocytopenia). This can result inundesirable and/or uncontrollable bleeding. Reduced inhibition of otherJAKs, such as JAK3 and Tyk2, may also be desirable as humans lackingfunctional version of these kinases have been shown to suffer fromnumerous maladies such as severe-combined immunodeficiency orhyperimmunoglobulin E syndrome (Minegishi, Y, et al. Immunity 25:745-55,2006; Macchi P, et al. Nature. 377:65-8, 1995). Therefore a JAK1inhibitor with reduced affinity for other JAKs would have significantadvantages over a less-selective inhibitor with respect to reduced sideeffects involving immune suppression, anemia and thrombocytopenia.

In some embodiments, the compound, or pharmaceutically acceptable saltthereof, is administered as an ophthalmic composition. Accordingly, insome embodiments, the methods comprise administration of the compound,or pharmaceutically acceptable salt thereof, and an ophthalmicallyacceptable carrier. In some embodiments, the ophthalmic composition is aliquid composition, semi-solid composition, insert, film, microparticlesor nanoparticles.

In some embodiments, the ophthalmic composition is a liquid composition.In some embodiments, the ophthalmic composition is a semi-solidcomposition. In some embodiments, the ophthalmic composition is atopical composition. The topical compositions include, but are notlimited to liquid and semi-solid compositions. In some embodiments, theophthalmic composition is a topical composition. In some embodiments,the topical composition comprises aqueous solution, an aqueoussuspension, an ointment or a gel. In some embodiments, the ophthalmiccomposition is topically applied to the front of the eye, under theupper eyelid, on the lower eyelid and in the cul-de-sac. In someembodiments, the ophthalmic composition is sterilized. The sterilizationcan be accomplished by known techniques like sterilizing filtration ofthe solution or by heating of the solution in the ampoule ready for use.The ophthalmic compositions of the invention can further containpharmaceutical excipients suitable for the preparation of ophthalmicformulations. Examples of such excipients are preserving agents,buffering agents, chelating agents, antioxidant agents and salts forregulating the osmotic pressure.

As used herein, the term “ophthalmically acceptable carrier” refers toany material that can contain and release the compound, orpharmaceutically acceptable salt thereof, and that is compatible withthe eye. In some embodiments, the ophthalmically acceptable carrier iswater or an aqueous solution or suspension, but also includes oils suchas those used to make ointments and polymer matrices such as used inocular inserts. In some embodiments, the composition may be an aqueoussuspension comprising the compound, or pharmaceutically acceptable saltthereof. Liquid ophthalmic compositions, including both ointments andsuspensions, may have a viscosity that is suited for the selected routeof administration. In some embodiments, the ophthalmic composition has aviscosity in the range of from about 1,000 to about 30,000 centipoise.

In some embodiments, the ophthalmic compositions may further compriseone or more of surfactants, adjuvants, buffers, antioxidants, tonicityadjusters, preservatives (e.g., EDTA, BAK (benzalkonium chloride),sodium chlorite, sodium perborate, polyquaterium-1), thickeners orviscosity modifiers (e.g., carboxymethyl cellulose, hydroxymethylcellulose, polyvinyl alcohol, polyethylene glycol, glycol 400, propyleneglycol hydroxymethyl cellulose, hydroxpropyl-guar, hyaluronic acid, andhydroxypropyl cellulose) and the like. Additives in the formulation mayinclude, but are not limited to, sodium chloride, sodium bicarbonate,sorbic acid, methyl paraben, propyl paraben, chlorhexidine, castor oil,and sodium perborate.

Aqueous ophthalmic compositions (solutions or suspensions) generally donot contain physiologically or ophthalmically harmful constituents. Insome embodiments, purified or deionized water is used in thecomposition. The pH may be adjusted by adding any physiologically andophthalmically acceptable pH adjusting acids, bases or buffers to withinthe range of about 5.0 to 8.5. Ophthalmically acceptable examples ofacids include acetic, boric, citric, lactic, phosphoric, hydrochloric,and the like, and examples of bases include sodium hydroxide, sodiumphosphate, sodium borate, sodium citrate, sodium acetate, sodiumlactate, tromethamine, trishydroxymethylamino-methane, and the like.Salts and buffers include citratedextrose, sodium bicarbonate, ammoniumchloride and mixtures of the aforementioned acids and bases.

In some embodiments, the methods involve forming or supplying a depot ofthe therapeutic agent in contact with the external surface of the eye. Adepot refers to a source of therapeutic agent that is not rapidlyremoved by tears or other eye clearance mechanisms. This allows forcontinued, sustained high concentrations of therapeutic agent to bepresent in the fluid on the external surface of the eye by a singleapplication. Without wishing to be bound by any theory, it is believedthat absorption and penetration may be dependent on both the dissolveddrug concentration and the contact duration of the external tissue withthe drug containing fluid. As the drug is removed by clearance of theocular fluid and/or absorption into the eye tissue, more drug isprovided, e.g. dissolved, into the replenished ocular fluid from thedepot. Accordingly, the use of a depot may more easily facilitateloading of the ocular tissue for more insoluble therapeutic agents. Insome embodiments, the depot can remain for up to eight hours or more. Insome embodiments, the ophthalmic depot forms includes, but is notlimited to, aqueous polymeric suspensions, ointments, and solid inserts.

In some embodiments, the ophthalmic composition is an ointment or gel.In some embodiment, the ophthalmic composition is an oil-based deliveryvehicle.

Common bases may include, but are not limited to,mineral oil, petrolatum and combinations thereof. In some embodiments,the ointment is applied as a ribbon onto the lower eyelid.

In some embodiment, the ophthalmic composition is an ophthalmic insert.In some embodiments, the ophthalmic insert is biologically inert, soft,bio-erodible, viscoelastic, stable to sterilization after exposure totherapeutic agents, resistant to infections from air borne bacteria,bio-erodible, biocompatible, and/or viscoelastic. In some embodiments,the insert comprises an ophthalmically acceptable matrix, e.g., apolymer matrix. The matrix is typically a polymer and the therapeuticagent is generally dispersed therein or bonded to the polymer matrix. Insome embodiments, the therapeutic agent may be slowly released from thematrix through dissolution or hydrolysis of the covalent bond. In someembodiments, the polymer is bioerodible (soluble) and the dissolutionrate thereof can control the release rate of the therapeutic agentdispersed therein. In another form, the polymer matrix is abiodegradable polymer that breaks down such as by hydrolysis to therebyrelease the therapeutic agent bonded thereto or dispersed therein. Infurther embodiments, the matrix and therapeutic agent can be surroundedwith an additional polymeric coating to further control release. In someembodiments, the insert comprises a biodegradable polymer such aspolycaprolactone (PCL), an ethylenevinyl acetate copolymer (EVA),polyalkyl cyanoacrylate, polyurethane, a nylon, or poly(dl-lactide-co-glycolide) (PLGA), or a copolymer of any of these. Insome embodiments, the therapeutic agent is dispersed into the matrixmaterial or dispersed amongst the monomer composition used to make thematrix material prior to polymerization. In some embodiments, the amountof therapeutic agent is from about 0.1 to about 50%, or from about 2 toabout 20%. In further embodiments, the biodegradable or bioerodiblepolymer matrix is used so that the spent insert does not have to beremoved. As the biodegradable or bioerodible polymer is degraded ordissolved, the therapeutic agent is released.

In further embodiments, the ophthalmic insert comprises a polymer,including, but are not limited to, those described in Wagh, et al.,“Polymers used in ocular dosage form and drug delivery systems”, AsianJ. Pharm., pages 12-17 (January 2008), which is incorporated herein byreference in its entirety.

In some embodiments,the aqueous polymeric suspensions may be formulated so that they retainthe same or substantially the same viscosity in the eye that they hadprior to administration to the eye. In some embodiments, they may beformulated so that there is increased gelation upon contact with tearfluid.

Labeled Compounds and Assay Methods

Another aspect of the present invention relates to labeled compounds ofthe invention (radio-labeled, fluorescent-labeled, etc.) that would beuseful not only in imaging techniques but also in assays, both in vitroand in vivo, for localizing and quantitating JAK in tissue samples,including human, and for identifying JAK ligands by inhibition bindingof a labeled compound. Accordingly, the present invention includes JAKassays that contain such labeled compounds.

The present invention further includes isotopically-labeled compounds ofthe invention. An “isotopically” or “radio-labeled” compound is acompound of the invention where one or more atoms are replaced orsubstituted by an atom having an atomic mass or mass number differentfrom the atomic mass or mass number typically found in nature (i.e.,naturally occurring). Suitable radionuclides that may be incorporated incompounds of the present invention include but are not limited to ³H(also written as T for tritium), ¹¹C, ¹³C, ¹⁴C, ¹³N, ¹⁵N, ¹⁵O, ¹⁷O, ¹⁸O,¹⁸F, ³⁵S, ³⁶Cl, ⁸²Br, ⁷⁵Br, ⁷⁶Br, ⁷⁷Br, ¹²³I, ¹²⁴I, ¹²⁵I and ¹³¹I. Theradionuclide that is incorporated in the instant radio-labeled compoundswill depend on the specific application of that radio-labeled compound.For example, for in vitro JAK labeling and competition assays, compoundsthat incorporate ³H, ¹⁴C, ⁸²Br, ¹²⁵I, ¹³¹I, ³⁵S or will generally bemost useful. For radio-imaging applications ¹¹C, ¹⁸F, ¹²⁵I, ¹²³I, ¹²⁴I,¹³¹I, ⁷⁵Br, ⁷⁶Br or ⁷⁷Br will generally be most useful.

It is to be understood that a “radio-labeled” or “labeled compound” is acompound that has incorporated at least one radionuclide. In someembodiments the radionuclide is selected from the group consisting of³H, ¹⁴C, ¹²⁵I, ³⁵S and ⁸²Br. In some embodiments, the compoundincorporates 1, 2, or 3 deuterium atoms.

The present invention can further include synthetic methods forincorporating radio-isotopes into compounds of the invention. Syntheticmethods for incorporating radio-isotopes into organic compounds are wellknown in the art, and an ordinary skill in the art will readilyrecognize the methods applicable for the compounds of invention.

A labeled compound of the invention can be used in a screening assay toidentify/evaluate compounds. For example, a newly synthesized oridentified compound (i.e., test compound) which is labeled can beevaluated for its ability to bind a JAK by monitoring its concentrationvariation when contacting with the JAK, through tracking of thelabeling. For example, a test compound (labeled) can be evaluated forits ability to reduce binding of another compound which is known to bindto a JAK (i.e., standard compound). Accordingly, the ability of a testcompound to compete with the standard compound for binding to the JAKdirectly correlates to its binding affinity. Conversely, in some otherscreening assays, the standard compound is labeled and test compoundsare unlabeled. Accordingly, the concentration of the labeled standardcompound is monitored in order to evaluate the competition between thestandard compound and the test compound, and the relative bindingaffinity of the test compound is thus ascertained.

Kits

The present invention also includes pharmaceutical kits useful, forexample, in the treatment or prevention of JAK-associated diseases ordisorders, such as cancer, which include one or more containerscontaining a pharmaceutical composition comprising a therapeuticallyeffective amount of a compound of the invention. Such kits can furtherinclude, if desired, one or more of various conventional pharmaceuticalkit components, such as, for example, containers with one or morepharmaceutically acceptable carriers, additional containers, etc., aswill be readily apparent to those skilled in the art. Instructions,either as inserts or as labels, indicating quantities of the componentsto be administered, guidelines for administration, and/or guidelines formixing the components, can also be included in the kit.

The invention will be described in greater detail by way of specificexamples. The following examples are offered for illustrative purposes,and are not intended to limit the invention in any manner. Those ofskill in the art will readily recognize a variety of non-criticalparameters which can be changed or modified to yield essentially thesame results. The compounds of the Examples have been found to be JAKinhibitors according to at least one assay described herein.

A salt screening studywas performed using pharmaceutically acceptable acids for the formationof crystalline Example 1 salts. Adipic acid was identified to give acrystalline Example 1 adipic acid salt. The initially obtained solidform (Form I) of Example 1 adipic acid salt with a melting point of 178°C. has been selected for optimization. This form is a crystalline formas verified by X-ray powder diffractometry (XRPD), differential scanningcalorimetry (DSC), and thermal gravimetric analysis (TGA). Thestoichiometry of the salt was determined to be 1:1 (freebase to adipicacid) by ¹H NMR spectroscopy and elemental analysis.

A polymorph screening study was performed on Example 1 adipate salt.Phase equilibration studies were carried out by slurrying the Form Icrystals in a variety of solvents (MeCN, CHCl₃, CH₂Cl₂, MIBK, MEK,acetone, toluene, hexane, heptane, THF, MTBE, EtOH, i-PrOH, n-BuOH,EtOAc, i-PrOAc at 25° C. or 50° C. At 25° C., all the solvents testedgave the same crystalline Form I after slurrying. At 50° C., the sameresults were observed with the exception of ethanol. The XRPD pattern ofthe solid obtained from ethanol slurry showed the presence of free basewhich can be explained by a simple salt dissociation. The results of thephase equilibration studies suggest Form I is a stable crystalline form.Moreover, multiple lots (from gram to kilogram scales) of Example 1adipic acid salt made to date have been determined to be the samecrystalline form (Form I). Seeding had been used to induce the formationof Form I in the crystallization. However, it was also observed thatForm I was obtained even without seeding in the crystallization.

Preparation: Adipic acid (790 g, 5.406 mol) was dissolved in methanol(29 L) at 16° C.2-(3-(4-(7H-Pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl)-1-(1-(3-fluoro-2-(trifluoromethyl)-isonicotinoyl)piperidin-4-yl)azetidin-3-yl)acetonitrilefree base (2.85 kg, 5.149 mol) was added to the adipic acid solution inmethanol at 16° C. The reaction mixture was heated under reflux for 2hours. The resulting reaction mixture was cooled to ambient temperatureand the solvent was removed by distillation under reduced pressure togive the crude adipic acid salt. The crude adipic acid salt wasdissolved in acetone (14 L) at ambient temperature. n-Heptane (20 L) wasadded over 2 hours to the crude adipic acid salt solution in acetone at18° C. to precipitate the salt. The resultant slurry was stirred at 18°C. for 1 hour. The salt was isolated by filtration. The wet cake waswashed with n-heptane (6 L). The product was dried on the filter funnelunder suction for 18 hours to afford the crude2-(3-(4-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl)-1-(1-(3-fluoro-2-(trifluoromethyl)-isonicotinoyl)piperidin-4-yl)azetidin-3-yl)acetonitrileadipic acid salt (3.572 kg, 5.105 mol, 99.2% yield) as a whitecrystalline solid.

Example A In Vitro JAK Kinase Assay

Compounds herein were tested for inhibitory activity of JAK targetsaccording to the following in vitro assay described in Park et al.,Analytical Biochemistry 1999, 269, 94-104. The catalytic domains ofhuman JAK1 (a.a. 837-1142), Jak2 (a.a. 828-1132) and Jak3 (a.a.781-1124) with an N-terminal His tag were expressed using baculovirus ininsect cells and purified. The catalytic activity of JAK1, JAK2 or JAK3was assayed by measuring the phosphorylation of a biotinylated peptide.The phosphorylated peptide was detected by homogenous time resolvedfluorescence (HTRF). IC₅₀s of compounds were measured for each kinase inthe 40 microL reactions that contain the enzyme, ATP and 500 nM peptidein 50 mM Tris (pH 7.8) buffer with 100 mM NaCl, 5 mM DTT, and 0.1 mg/mL(0.01%) BSA. For the 1 mM IC₅₀ measurements, ATP concentration in thereactions was 1 mM. Reactions were carried out at room temperature for 1hr and then stopped with 20 μL 45 mM EDTA, 300 nM SA-APC, 6 nM Eu-Py20in assay buffer (Perkin Elmer, Boston, Mass.). Binding to the Europiumlabeled antibody took place for 40 minutes and HTRF signal was measuredon a Fusion plate reader (Perkin Elmer, Boston, Mass.). See Table 1 fordata related to compounds of the invention.

Example B Cellular Assays

Cancer cell lines dependent on cytokines and hence JAK/STAT signaltransduction, for growth, can be plated at 6000 cells per well (96 wellplate format) in RPMI 1640, 10% FBS, and 1 nGmL of appropriate cytokine.Compounds can be added to the cells in DMSO/media (final concentration0.2% DMSO) and incubated for 72 hours at 37° C., 5% CO₂. The effect ofcompound on cell viability is assessed using the CellTiter-GloLuminescent Cell Viability Assay (Promega) followed by TopCount (PerkinElmer, Boston, Mass.) quantitation. Potential off-target effects ofcompounds are measured in parallel using a non-JAK driven cell line withthe same assay readout. All experiments are typically performed induplicate.

The above cell lines can also be used to examine the effects ofcompounds on phosphorylation of JAK kinases or potential downstreamsubstrates such as STAT proteins, Akt, Shp2, or Erk. These experimentscan be performed following an overnight cytokine starvation, followed bya brief preincubation with compound (2 hours or less) and cytokinestimulation of approximately 1 hour or less. Proteins are then extractedfrom cells and analyzed by techniques familiar to those schooled in theart including Western blotting or ELISAs using antibodies that candifferentiate between phosphorylated and total protein. Theseexperiments can utilize normal or cancer cells to investigate theactivity of compounds on tumor cell survival biology or on mediators ofinflammatory disease. For example, with regards to the latter, cytokinessuch as IL-6, IL-12, IL-23, or IFN can be used to stimulate JAKactivation resulting in phosphorylation of STAT protein(s) andpotentially in transcriptional profiles (assessed by array or qPCRtechnology) or production and/or secretion of proteins, such as IL-17.The ability of compounds to inhibit these cytokine mediated effects canbe measured using techniques common to those schooled in the art.

Compounds herein can also be tested in cellular models designed toevaluate their potency and activity against mutant JAKs, for example,the JAK2V617F mutation found in myeloid proliferative disorders. Theseexperiments often utilize cytokine dependent cells of hematologicallineage (e.g. BaF3) into which the wild-type or mutant JAK kinases areectopically expressed (James, C., et al. Nature 434:1144-1148; Staerk,J., et al. JBC 280:41893-41899). Endpoints include the effects ofcompounds on cell survival, proliferation, and phosphorylated JAK, STAT,Akt, or Erk proteins.

Certain compounds herein can be evaluated for their activity inhibitingT-cell proliferation. Such as assay can be considered a second cytokine(i.e. JAK) driven proliferation assay and also a simplistic assay ofimmune suppression or inhibition of immune activation. The following isa brief outline of how such experiments can be performed. Peripheralblood mononuclear cells (PBMCs) are prepared from human whole bloodsamples using Ficoll Hypaque separation method and T-cells (fraction2000) can be obtained from PBMCs by elutriation. Freshly isolated humanT-cells can be maintained in culture medium (RPMI 1640 supplementedwith10% fetal bovine serum, 100 Uml penicillin, 100 μg/ml streptomycin)at a density of 2×10⁶ cellsml at 37° C. for up to 2 days. For IL-2stimulated cell proliferation analysis, T-cells are first treated withPhytohemagglutinin (PHA) at a final concentration of 10 μgmL for 72 h.After washing once with PBS, 6000 cellswell are plated in 96-well platesand treated with compounds at different concentrations in the culturemedium in the presence of 100 U/mL human IL-2 (ProSpec-Tany TechnoGene;Rehovot, Israel). The plates are incubated at 37° C. for 72h and theproliferation index is assessed using CellTiter-Glo Luminescent reagentsfollowing the manufactory suggested protocol (Promega; Madison, Wis.).

Example C In Vivo Anti-Tumor Efficacy

Compounds herein can be evaluated in human tumor xenograft models inimmune compromised mice. For example, a tumorigenic variant of the INA-6plasmacytoma cell line can be used to inoculate SCID mice subcutaneously(Burger, R., et al. Hematol J. 2:42-53, 2001). Tumor bearing animals canthen be randomized into drug or vehicle treatment groups and differentdoses of compounds can be administered by any number of the usual routesincluding oral, i.p., or continuous infusion using implantable pumps.Tumor growth is followed over time using calipers. Further, tumorsamples can be harvested at any time after the initiation of treatmentfor analysis as described above (Example B) to evaluate compound effectson JAK activity and downstream signaling pathways. In addition,selectivity of the compound(s) can be assessed using xenograft tumormodels that are driven by other know kinases (e.g. Bcr-Abl) such as theK562 tumor model.

Example D Murine Skin Contact Delayed Hypersensitivity Response Test

Compounds herein can also be tested for their efficacies (of inhibitingJAK targets) in the T-cell driven murine delayed hypersensitivity testmodel. The murine skin contact delayed-type hypersensitivity (DTH)response is considered to be a valid model of clinical contactdermatitis, and other T-lymphocyte mediated immune disorders of theskin, such as psoriasis (Immunol Today. 1998 January; 19(1):37-44).Murine DTH shares multiple characteristics with psoriasis, including theimmune infiltrate, the accompanying increase in inflammatory cytokines,and keratinocyte hyperproliferation. Furthermore, many classes of agentsthat are efficacious in treating psoriasis in the clinic are alsoeffective inhibitors of the DTH response in mice (Agents Actions. 1993January; 38(1-2):116-21).

On Day 0 and 1, Balbc mice are sensitized with a topical application, totheir shaved abdomen with the antigen 2,4,dinitro-fluorobenzene (DNFB).On day 5, ears are measured for thickness using an engineer'smicrometer. This measurement is recorded and used as a baseline. Both ofthe animals' ears are then challenged by a topical application of DNFBin a total of 20 μL (10 μL on the internal pinna and 10 μL on theexternal pinna) at a concentration of 0.2%. Twenty-four to seventy-twohours after the challenge, ears are measured again. Treatment with thetest compounds is given throughout the sensitization and challengephases (day −1 to day 7) or prior to and throughout the challenge phase(usually afternoon of day 4 to day 7). Treatment of the test compounds(in different concentration) is administered either systemically ortopically (topical application of the treatment to the ears). Efficaciesof the test compounds are indicated by a reduction in ear swellingcomparing to the situation without the treatment. Compounds causing areduction of 20% or more were considered efficacious. In someexperiments, the mice are challenged but not sensitized (negativecontrol).

The inhibitive effect (inhibiting activation of the JAK-STAT pathways)of the test compounds can be confirmed by immunohistochemical analysis.Activation of the JAK-STAT pathway(s) results in the formation andtranslocation of functional transcription factors. Further, the influxof immune cells and the increased proliferation of keratinocytes shouldalso provide unique expression profile changes in the ear that can beinvestigated and quantified. Formalin fixed and paraffin embedded earsections (harvested after the challenge phase in the DTH model) aresubjected to immunohistochemical analysis using an antibody thatspecifically interacts with phosphorylated STAT3 (clone 58E12, CellSignaling Technologies). The mouse ears are treated with test compounds,vehicle, or dexamethasone (a clinically efficacious treatment forpsoriasis), or without any treatment, in the DTH model for comparisons.Test compounds and the dexamethasone can produce similar transcriptionalchanges both qualitatively and quantitatively, and both the testcompounds and dexamethasone can reduce the number of infiltrating cells.Both systemically and topical administration of the test compounds canproduce inhibitive effects, i.e., reduction in the number ofinfiltrating cells and inhibition of the transcriptional changes.

Example E In Vivo Anti-Inflammatory Activity

Compounds herein can be evaluated in rodent or non-rodent modelsdesigned to replicate a single or complex inflammation response. Forinstance, rodent models of arthritis can be used to evaluate thetherapeutic potential of compounds dosed preventatively ortherapeutically. These models include but are not limited to mouse orrat collagen-induced arthritis, rat adjuvant-induced arthritis, andcollagen antibody-induced arthritis. Autoimmune diseases including, butnot limited to, multiple sclerosis, type I-diabetes mellitus,uveoretinitis, thyroditis, myasthenia gravis, immunoglobulinnephropathies, myocarditis, airway sensitization (asthma), lupus, orcolitis may also be used to evaluate the therapeutic potential ofcompounds herein. These models are well established in the researchcommunity and are familiar to those schooled in the art (CurrentProtocols in Immunology, Vol 3., Coligan, J. E. et al, Wiley Press.;Methods in Molecular Biology: Vol. 225, Inflammation Protocols.,Winyard, P. G. and Willoughby, D. A., Humana Press, 2003).

Example F Animal Models for the Treatment of Dry Eye, Uveitis, andConjunctivitis

Agents may be evaluated in one or more preclinical models of dry eyeknown to those schooled in the art including, but not limited to, therabbit concanavalin A (ConA) lacrimal gland model, the scopolamine mousemodel (subcutaneous or transdermal), the Botulinumn mouse lacrimal glandmodel, or any of a number of spontaneous rodent auto-immune models thatresult in ocular gland dysfunction (e.g. NOD-SCID, MRLlpr, or NZB/NZW)(Barabino et al., Experimental Eye Research 2004, 79, 613-621 andSchrader et al., Developmental Opthalmology, Karger 2008, 41, 298-312,each of which is incorporated herein by reference in its entirety).Endpoints in these models may include histopathology of the ocularglands and eye (cornea, etc.) and possibly the classic Schirmer test ormodified versions thereof (Barabino et al.) which measure tearproduction. Activity may be assessed by dosing via multiple routes ofadministration (e.g. systemic or topical) which may begin prior to orafter measurable disease exists.

Agents may be evaluated in one or more preclinical models of uveitisknown to those schooled in the art. These include, but are not limitedto, models of experimental autoimmune uveitis (EAU) and endotoxininduced uveitis (EIU). EAU experiements may be performed in the rabbit,rat, or mouse and may involve passive or activate immunization. Forinstance, any of a number or retinal antigens may be used to sensitizeanimals to a relevant immunogen after which animals may be challengedocuarly with the same antigen. The EIU model is more acute and involveslocal or systemic administration of lipopolysaccaride at sublethaldoses. Endpoints for both the EIU and EAU models may include fundoscopicexam, histopathology amongst others. These models are reviewed by Smithet al. (Immunology and Cell Biology 1998, 76, 497-512, which isincorporated herein by reference in its entirety). Activity is assessedby dosing via multiple routes of administration (e.g. systemic ortopical) which may begin prior to or after measurable disease exists.Some models listed above may also develop scleritisepiscleritis,chorioditis, cyclitis, or iritis and are therefore useful ininvestigating the potential activity of compounds for the therapeutictreatment of these diseases.

Agents may also be evaluated in one or more preclinical models ofconjunctivitis known those schooled in the art. These include, but arenot limited to, rodent models utilizing guinea-pig, rat, or mouse. Theguinea-pig models include those utilizing active or passive immunizationand/or immune challenge protocols with antigens such as ovalbumin orragweed (reviewed in Groneberg, D. A., et al., Allergy 2003, 58,1101-1113, which is incorporated herein by reference in its entirety).Rat and mouse models are similar in general design to those in theguinea-pig (also reviewed by Groneberg). Activity may be assessed bydosing via multiple routes of administration (e.g. systemic or topical)which may begin prior to or after measurable disease exists. Endpointsfor such studies may include, for example, histological, immunological,biochemical, or molecular analysis of ocular tissues such as theconjunctiva.

Example G In Vivo Protection of Bone

Compounds may be evaluated in various preclinical models of osteopenia,osteoporosis, or bone resorption known to those schooled in the art. Forexample, ovariectomized rodents may be used to evaluate the ability ofcompounds to affect signs and markers of bone remodeling and/or density(W. S. S. Jee and W. Yao, J Musculoskel. Nueron. Interact., 2001, 1(3),193-207, which is incorporated herein by reference in its entirety).Alternatively, bone density and architecture may be evaluated in controlor compound treated rodents in models of therapy (e.g. glucocorticoid)induced osteopenia (Yao, et al. Arthritis and Rheumatism, 2008, 58(6),3485-3497; and id. 58(11), 1674-1686, both of which are incorporatedherein by reference in its entirety). In addition, the effects ofcompounds on bone resorption and density may be evaluable in the rodentmodels of arthritis discussed above (Example E). Endpoints for all thesemodels may vary but often include histological and radiologicalassessments as well as immunohisotology and appropriate biochemicalmarkers of bone remodeling.
